What does it mean to be a billionth of a meter?

Nanotechnology is the study of materials at the subatomic level - materials that are smaller than an atom. A nanometer is one-billionth of a meter. To put things in perspective- if the Earth was 1 meter, a marble next to it would represent 1 nanometer.

Nanotechnology deals with things at the dimension where reality is unlike what we deal with every day, described by classic physics. Materials at this small scale change significantly in regards to their physical and chemical properties. Materials have enhanced properties, such as high strength while being very lightweight. Gravity becomes irrelevant as intermolecular forces become…


Quantifying the problem

According to UNICEF, one in five school-aged children aren’t in school at all.

An estimated 617 million children and youth are unable to achieve a minimum level of proficiency in reading and math, even though two-thirds of them are in school.

This shows that lack of formal education isn’t the only problem. Around the world with unequal access to quality education, being in school doesn’t always mean learning.

Schooling does not always lead to learning. Worldwide, there are more non-learners in school than out of school. UNICEF

The global cost of illiteracy is $1.19 Trillion. According to a report, 37…


As intelligent beings, when we see anything, we are able to give it context from our previous knowledge. We don’t always need to know everything about a given object to know what it is. For example, if you see a desk and behind it only the top part of something, you’ll know that the object behind the desk is a chair because of the construct of the object as well as the knowledge that with a desk there is almost always a chair.

This exact task isn’t as easy for a computer.

A computer needs thousands of human-labeled images from…


Urbanization and the 2030 Agenda:

Cities play a very important role in our society. More than 80% of the global GDP is generated in cities. Right now, more than half of the world population lives in urban cities which are estimated to be two-thirds by 2050.

As urbanization continues to be a major trend, cities need to be more inclusive, sustainable, and accommodating. People are striving to live a high standards lifestyle. But with exponential population growth, but the same amount of land (and resources)- the earth cannot simply entertain us all.

As we move closer to the 2030 Agenda deadline, our hopes to achieving…

Urban housing

To accommodate the growing urban population, more affordable and adequate housing needs to be arranged.

In urban areas, people have to sacrifice the functions of their homes to get a place that ticks off either of the following: good location, size, or budget.

In the bustling dynamics of a city with a growing population, space is scarce. The u-turns in hopes of finding a parking lot, checking up with the restaurant you love to find a reservation at, and countless hours viewing apartments that fit your budget is not only exhausting but is also time-consuming. …


“Life is a flywheel”.

I heard about the concept of the flywheel during a youtube binge. It didn’t seem more than a catchphrase waiting for dismissal.

It came up again in a very consuming podcast. And it stuck big time. Applying the concept of the flywheel on our lives, I realized that our life is built on moments, one leading to another. It’s how you spend your hours that accumulate into how your day turned out. And your days go on becoming weeks, weeks turning into months and months change into fleeting years. …
